HP R1500 G2 UPS USB HID Usage Tables

Hello!

Our HP server using arch linux is not supposed to be running with monitor attached so we have no use of HPPM since it doesn't give any valuable information via cli access (or maybe I just can't find the real way?). Trying to use NUT (network ups tools) with tripplite-hid subdriver gives just a partial success - several of HID objects are unknown to NUT and it shows battery temperature -238 degrees or so..That's why I'm interested in correct HP implemented USB HID usage tables for R1500 G2 UPS. Where could I get them to create new usbhid subdriver in NUT?
